Blow-through feeder/airlock

Designed to ensure optimal bulk density and throughput of hard-to-convey materials in high-pressure pneumatic conveying applications, the BT Series Blow-Through Feeder/Airlock from ACS Valves can over-aerate and reduce material feed efficiency. The product’s design decreases excess aeration of the material during conveying with an integrated vent port on the return side of the valve housing that automatically vents air leakage. The BT Series 8 vane rotary valve design significantly reduces air leakage and maximizes the flow path of air through the rotor pocket; improving material pocket release. The minimal air leakage, and resulting low, effective pressure drop of the BT Series optimizes material flow density, improves material conveying efficiency, and reduces total compressed air consumption, according to the manufacturer.

The BT Series housings are CNC-machined to precise tolerances to ensure extended duty cycles by eliminating axial shaft movement, seal leakage and shortened bearing life. Maintenance cycles are further extended with an outboard bearing design that removes the bearings from the path of damaging and contaminating materials. The product’s housings are available in cast iron or 304 or 316 stainless steel, in either 8-in. or 10-in., round flange sizes. The BT Series is available with a hard chrome housing interior, with adjustable rotor tips. — ACS Valves,
